The Study
Effects of 12 Weeks of Whole-Body Vibration Training and Vitamin D Supplementation on Bone Density and Muscle Quality in the Aged with Osteosarcopenia: A Randomized Controlled Trial
This study saw that people who did vibration training and took vitamin D seemed to get stronger and have better bones than those who just took vitamin D — but we don’t know if the training actually caused it, because we can’t be sure the groups were chosen fairly.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Older people with weak bones and muscles did a special vibrating platform exercise and took vitamin D. Their bones got stronger, muscles grew a bit, and they could stand up and walk better.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — stronger bones and muscles mean less fall risk and better independence for older adults.
- 2Bones got denser, muscles increased, grip strength improved, walking and chair stands got faster, irisin went up, myostatin went down.

Claims (5)
If older people with weak muscles and bones do vibration exercises and take vitamin D pills, their hand strength might get better.
When older people with weak bones and muscles do whole-body vibration exercises and take vitamin D pills, their bodies seem to produce more of a helpful muscle protein (irisin) and less of a muscle-limiting protein (myostatin).
If older people with weak bones and muscles do vibration exercises and take vitamin D pills, their bones might get stronger, especially in the lower back, hips, and forearms.
If older people with weak muscles and bones do whole-body vibration exercises and take vitamin D pills, their arm and leg muscles might get stronger.
When older people with weak bones and muscles do vibration exercises and take vitamin D pills, they tend to get better at standing up from a chair, walking faster, and moving around more easily.
